Currently, all I do in my UpdateAsync calls, is return a value, but can I do any kind of checks in the call to ensure that data is saved, and no data loss can ensue?
Example DataStore
local Players = game:GetService("Players")
local DataStoreService = game:GetService("DataStoreService")
local PlayerData = DataStoreService:GetDataStore("PlayerData")
local closing = false — to know if the game is closing down
local function save(player)
local dataHolder = player:WaitForChild("Data")
local cash = dataHolder.Cash
local rank = dataHolder.Rank
local data = {
Cash = cash.Value,
Rank = rank.Value
}
local success, err = nil
do
local tries = 0
repeat
success, err = pcall(function)
PlayerData:UpdateAsync(player.UserId.."-data", function()
— can I do any additional checks here?
return data
end)
end)
tries += 1
until success or tries > 3
end
if not success then
warn("There was an error whilst saving", player.Name.."’s data!")
warn("Error:", err)
end
end
Players.PlayerAdded:Connect(function(player)
local dataHolder = player:WaitForChild("Data")
local cash = dataHolder.Cash
local rank = dataHolder.Rank
local data = nil
local success, err = nil
do
local tries = 0
repeat
success, err = pcall(function()
data = PlayerData:GetAsync(player.UserId.."-data")
end)
tries += 1
until success or tries > 3
end
if success then
if data then
cash.Value = data.Cash
rank.Value = data.Rank
else
— set default values
end
else
warn("There was an error whilst getting", player.Name.."’s data!")
warn("Error:", err)
player:Kick("You were kicked in an attempt to preserve your data!")
end
end)
coroutine.wrap(function()
while not closing do
local autoSaveInterval = math.random(480,720) — 8-12 minutes
for _, player in ipairs(Players:GetPlayers()) do
coroutine.wrap(save)(player)
end
wait(autoSaveInterval)
end
end)()
Players.PlayerRemoving:Connect(function()
if closing then — if the game is closing down, don’t save!
return
end
save(player)
end)()
game:BindToClose(function()
closing = true
for _, player in ipairs(Players:GetPlayers()) do
coroutine.wrap(save)(player)
end
end)
